Bolt screwing monitoring method and system based on BIM

Abstract

The invention relates to a BIM-based bolt screwing monitoring method and system. The BIM-based bolt screwing monitoring method comprises steps that a construction part identification code selected in a BIM model is displayed on display equipment of an operation end; the bolt positions and the screwing sequence of the construction part are displayed on the display equipment; the operation end sends screwing information to the cloud end, the screwing information at least comprises screwing time and first information, and the first information is generated after an identification code corresponding to a selected construction part in a BIM model is scanned; the cloud side judges a screwing state of the bolt at the construction part according to the screwing information, wherein the screwing state comprises screwing times and screwing time; the cloud end issues the information of the screwing state to a display device of the operation end; and the screwing state of the bolt at the construction part is displayed on display equipment of the operation end. According to the method, workers can be guided to carry out construction according to a correct screwing sequence.

Description

technical field [0001] The present application relates to the technical field of construction process monitoring, in particular to a BIM-based bolt tightening monitoring method and system. Background technique [0002] High-strength bolts are bolts made of high-strength steel, which are widely used in the field of bridge construction. In the construction process of high-strength tightening of bridges, the relevant standards of our country have clearly stipulated that each bolt must undergo two tightenings, which are called the initial tightening and the final tightening, and the tools used for the initial tightening and final tightening must be strictly designed. distinguish. At the same time, the bolts of each gusset plate must be constructed in sequence. [0003] However, in the actual process, the number of bolts on a gusset plate is large, and construction workers generally do not have a clear understanding and understanding of the tightening sequence of high-strength ...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual process, the number of bolts on a gusset plate is large, and construction workers generally do not have a clear understanding and understanding of the tightening sequence of high-strength bolts. Even after training, it is difficult to tighten the bolts in the set sequence. It is also difficult to check the torque of each bolt, which will lead to a large gap between the prestress of the bolt and the design value, which will bring hidden dangers to the safety of the bridge structure

If the bolts are numbered directly on the gusset plate through paint, there will be unsightly problems
